Again after launching the remote application the gui freezes badly and get same set of exceptions
i think jaws is trying to read a user prefernce role but unable to do so
OR there could be a problem in Merlin1.4.0-beta-build 54 also !!

Updating the bug after getting mails from conerned Engineers

This bug is repeating on following configuration after being verified by me :-
JRE 1.4.0 - b58 mixed mode
JaWS1.0.1-build 09
Solaris Sparc 8

Following are the exceptions:-
javasoft4:/home/vv121044/jaws 101 % javaws/javaws
javasoft4:/home/vv121044/jaws 102 % Apr 2, 2001 12:59:34 PM java.util.prefs.FileSystemPreferences$7 run
WARNING: java.io.IOException: Permission denied


These are the steps to reproduce:-
1.Install JRE1.4.0 build 58 in your root (i installed it in /downloads which is one of the partitions on my machine)
2.java -version gives ouput:-java version "1.4.0-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta-b58)
Java HotSpot(TM) Client VM (build 1.4.0-beta-b58, mixed mode)
3.Either install a fresh javaws or change javaws.cfg to point to JRE1.4.0-b58
4.Launch Jaws it launches with following exception on terminal window
javasoft4:/home/vv121044/jaws 101 % javaws/javaws
javasoft4:/home/vv121044/jaws 102 % Apr 2, 2001 12:59:34 PM java.util.prefs.FileSystemPreferences$7 run
WARNING: java.io.IOException: Permission denied

P.S:- This time closing jaws did not log-off Xsession instead the prompt did not return to normal so Ctrl + C got the prompt back , also there was no running java thread .
See here:-
javasoft4:/home/vv121044/jaws 105 % javaws
javasoft4:/home/vv121044/jaws 106 % Apr 2, 2001 2:32:59 PM java.util.prefs.FileSystemPreferences$7 run
WARNING: java.io.IOException: Permission denied
^C
javasoft4:/home/vv121044/jaws 106 %



Could not reproduce the samae problem on other machine .
Installed jdk and javaws on other solaris sparc machine viz. xanadu and tested
bug , The bug did not reproduce . This time installation (both jdk and javaws) was done in home directory viz. /home/ra122198/ and the bug did not reproduce.

While filing the bug for first time also i could not reproduce this on this xanadu's machine whereas on other machine javasoft27 this bug was being reproduced ! Could not analyse the reason of inconsistency of reproducibility of this bug !!

if possible do advise me how to eliminate this problem from my machine since i have uninstalled all the version of jdks from my machine and install again to retest this bug . Same query has been raised earlier to andy herrick .
